Explain why aquatic amphibians constantly take on water but lose ions to their environment.

2) List the energy saving adaptations that help aquatic amphibians manage the challenges of living in a dilute environment as efficiently as possible.

3) Why isn’t the production of uric acid an adaptation of aquatic amphibians?

4) Why is ammonia a safe waste product for amphibians to produce, but would be lethal to desert reptiles and mammals?

5) Given the adaptations of aquatic amphibians’ renal systems, hypothesize what would happen to the osmolality of their body fluids over a short period of time if they were removed from their freshwater environment and placed in a desiccating environment such as a dry rock in the hot sun or a salty pond.
